352 FLORA OF SOUTH AMERICA. 



cseterum filiformia, glabra. Ovarium basi glabrum, apice 

 villosissirnum (in M. scandente pilis paucis apice coronatum), 

 carnosulum, complete biloculare. Ovula 4, adscendentia. 

 Stylus filiformis, apice coronatum stigmate crasso late orbi- 

 culato obscure bilobo. 



The climbing stem distinguishes this species from M. erecta 

 and M. glabra, the smooth leaves from M. spectabilis. In 

 habit and leaves it comes nearest to M. scandens ; but the, 

 dense inflorescence, smooth outer sepals, and scarcely visible 

 bracts, sufficiently distinguish it. 



882. M. scandens, Aubl. PI. Guian. 1, p. 230, t. 91, vix 

 Chois.; caule scandente glabro, foliis ovato-ellipticis breviter 

 acuminatis glabris, paniculse terminalis pubescentis pedun- 

 culis laxe cymiferis, bracteis bracteolisque ovatis squamse- 

 formibus, sepalis sericeo-pubescentibus cinereis, corolla sen- 

 ceo-villosa. — British Guiana, Schomburgk, 2nd Coll. n. 110 

 (46). Also Surinam, Hostmann, n. 1251. 



This agrees with Aublet's description and figure in every 

 thing except the size of the corolla, which is near l| inch 

 long, and not so deeply divided as is represented by Aublet ; 

 but his drawing has every appearance of being made from 

 an unexpanded bud, as the branch he figures has none but 

 young buds. Choisy's character differs from all specimens 1 

 have seen, as well as from Aublet's description and figure, 

 especially in the cordate leaves. 



883. M. sp. n. ?— Different from either of the above; but 

 my specimen is insufficient for description. — British Guiana, 

 Richard Schomburgk, n. (1469).

 B. edulis y platanifolia, Chois. 1. c. from Schomburgk's num-

 calyx and corolla of B. paniculata, and are in every respect at 

 variance with the cut-leaved varieties of B. edulis. — Waste
